On a future Earth ravaged by aliens and 50 years of global war, a civilization emerges that rejects the old ways to forge a new destiny in a wild frontier. Can the connection between a lawman trying to keep his town safe and a new kind of gold rush in San Francisco hold the only hope for a better future?

The game combines the intense action of a “AAA” console shooter, with the persistence, scale, and customization of an MMO, while its TV counterpart weaves the rich tapestry of the world into a series with the scope, characters, and drama of a classic sci-fi epic. Because they exist in a single universe, the show and the game will influence each other and evolve together over time, with actions in both mediums driving the overall story of  Defiance.

The Silicon Valley content raises all new questions for the Defiance universe.

Within the world expansion, players will find Karl Von Back has disappeared into Silicon Valley with his EGO-imbued followers, but it’s not the paradise they promised. The valley is overrun with Grid, and a strange cult, the Pilgrims of the Guiding Light, have taken hold in locations across the zone. As all new mysteries unravel, the populace of Silicon Valley calls for help, and only ark hunters have what it takes to face the trials ahead.

Silicon Valley is an all-new, completely free world expansion to Trion's ever-growing game, launching on Tuesday, August 5.

Defiance recently became free-to-play on PC and will be free-to-play on Xbox 360 and PS3 later this year.
